CAR-TRUCK- Specification of Letters Patent.

Patented July 3, 1906.

To all whom, it may concern.-

Beit known that I, ETHAN I. DoDDs, a citizen of the United States, residing at Pullman, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Car-Trucks, of which the following is a specification.

My invention concerns the equalizing means for the journal-boxes of a railway-car truck and when embodied in a six-wheel truck comprises an equalizing-bar integral with each end j ournal-box, the inner ends of the bars being pivoted to the opposite sides of the center j ournal-box on the same side of the truck. Such a construction eliminates the need of the usual pedestal tie-bars, since the pedestals are connected together indirectly through the journal-boxes and the equaliZing-bars.

In the accompanying drawings I have illustrated the preferred mechanical embodiment of my invention, wherein- Figure 1 is a side elevation of a six-wheel truck embodying my invention. Fig. 2 is a partial plan view, partly in section, of the truck illustrated in Fig. 1. Fig. 3 is a perspective view of one of the end j ournal-boxes and its integral equaliZing-bar, and Fig. 4 is a perspective view of one of the central journalboxes.

The truck includes the usual Wheel-pieces 10, each equipped with pedestals 11, l2, and 13, within which are slidably mounted journal-boxes 14, l5, and 16. End boxes 14 and 16 are each provided with an integral equalizing-bar 17 and 18, respectively, which project from the inner sides of the boxes in the manner illustrated most clearly in Figs. 1 and 3. Since all the end journal-boxes are substantially the same, a description of the one shown in Fig. 3 will suffice for all. Box 14 is supplied with the usual side guides 19, which coperate with the pedestal to maintain the box in position. Equalizing-bar 17 has upper and lower marginal integral anges 20 and 21, respectively, and on its upper surface is also supplied With an integral spring-seat 22, having an integral upstanding circular flange 23 to retain the spring in position, and the integral supporting bracket-pieces 24 uniting the sides of the bar with the under surface of the seat. At its outer end bar 17 j has a transverse elongated aperture 25 for a purpose described hereinafter.

Journal-box 15 (shown in perspective in Fig. 4 and in end elevation in Fig. 1) has the usual side guides 26, sliding on edestal 12, and also has projecting from eac side a pair of apertured integral spaced lugs or ears 27, between which the ends of equalizing-bars 17 and 18 are adapted to fit, pins 28 having the cotters 29 through their ends passing through the apertures of the lugs and bars to securely hold the same in place, the elongated apertures 25 permitting the boxes to shift position relatively to one another. As shown in Fig. 2, it will be seen that the bars and lugs are located between the inner and outer plates of pedestal 12, forming a neat and at the same time strong construction. The weight thrust upon springs 3() is transmitted through the equaliZing-bars directly to the end journal-boxes 14 and 16 and indirectly through the pivoted connections to the center journalbox 15, thereby distributing the load.

It may also be noted that by tying the outer journal-boxes to the center ones the pedestals are indirectly connected together, so that there is no need for employing the usual pedestal tie-bars.

This atent is intended to embrace only so much oi the disclosure made herein as is covered by the claims.

I claim- 1. In a railway-car truck, the combination of a plurality of j ournal-boxes and an equalizing-bar integral with one of said boxes and pivoted to another tially as described.

2. A six-wheel car-truck having its end j ournal-boxes each provided with an integral equalizing-bar, the inner ends of said bars being ivoted to the corresponding central journaloX, substantially as described.

3. A six-Wheel car-truck having central journal-boxes provided witha ertureds aced lugs projectin from each si e thereo and its end journa -boxes each equipped with an integral equalizing-bar, the free ends of which latter are apertured and fitted between the lugs of the corresponding central journal` box, and pins passing through the apertures of said lugs and bars holding the parts together, substantially as described.
